1. A method of a base station for transmitting a signal to a user equipment using two or more bands set in different TDD (Time Division Duplex) configurations, the method comprising: transmitting, to a first user equipment supporting different TDD configurations of an inter-band carrier aggregation, an enquiry message for a user equipment capability, and transmitting, to a second user equipment that does not support an inter-band carrier agreement, an enquiry message for a user equipment capability; receiving a user equipment capability information message including transmission mode information of the first user equipment, in response to the enquiry message transmitted to the first user equipment, wherein the transmission mode information of the first user equipment includes information indicating whether the first user equipment operates in a full-duplex mode or a half-duplex mode in two or more bands set in different TDD configurations of an inter-band carrier aggregation; in response to the enquiry message transmitted to the second user equipment, receiving, from the second user equipment that does not support an inter-band carrier agreement, a user equipment capability information message that does not include transmission mode information of the second user equipment in UE Capability Information Element (IE) of the second user equipment; determining the different TDD configurations of an inter-band carrier aggregation for the first user equipment according to a report of the transmission mode information of the first user equipment; transmitting, to the first user equipment, control information for configuring component carrier aggregation comprising component carriers using the two or more bands; and transmitting a signal to the first user equipment through the component carrier aggregation according to the transmission mode information, wherein the transmission mode information of the first user equipment is included in UE Capability IE of the first user equipment.
A base station communicates with user devices using multiple frequency bands configured with different TDD (Time Division Duplex) settings. The base station sends a capability request to a user device that supports carrier aggregation across bands with different TDD configurations, and sends a different capability request to a user device that *doesn't* support such carrier aggregation. The base station receives the first user device's capabilities, including whether it can operate in full-duplex or half-duplex mode across the multiple bands with different TDD settings. For the second user device, the capability information lacks duplex mode details. Based on the first user device's reported duplex capability, the base station configures carrier aggregation using the multiple bands. Finally, the base station transmits signals to the first user device using the configured carrier aggregation, considering the device's reported duplex mode capabilities which are included in UE Capability Information Element (IE).
2. The method as claimed in claim 1 , wherein the UE Capability IE of the first user equipment corresponds to a UE-EUTRA-Capability information element (IE), and the UE-EUTRA-Capability information element includes information about at least one band combination among the two or more bands.
The UE Capability Information Element (IE) mentioned previously in the base station communication method corresponds to a UE-EUTRA-Capability information element (IE). This UE-EUTRA-Capability information element includes information about at least one band combination among the two or more bands used for carrier aggregation with different TDD configurations. Therefore the base station uses this information about valid band combinations from the UE-EUTRA-Capability information element (IE) during the carrier aggregation configuration process.
3. The method as claimed in claim 2 , wherein the transmission mode information corresponds to the band combination.
The transmission mode information (full or half duplex) reported by the user equipment to the base station corresponds to the specific band combination being used in the carrier aggregation. Therefore, the base station considers the supported duplex mode for the *specific combination* of bands configured with different TDD settings, ensuring compatibility and optimal performance.
4. A method of a user equipment for receiving a signal from a base station using two or more bands set in different TDD (Time Division Duplex) configurations, the method comprising: receiving, by the user equipment supporting different TDD configurations of an inter-band carrier aggregation, an enquiry message for a user equipment capability from the base station; transmitting a user equipment capability information message, including transmission mode information of the user equipment, in response to the enquiry message, wherein the transmission mode information includes information indicating that the user equipment operates in a full-duplex mode in two or more bands set in different TDD configurations of an inter-band carrier aggregation; receiving, from the base station, control information for configuring component carrier aggregation comprising component carriers using the two or more bands; and receiving a signal from the base station through the component carrier aggregation according to the transmission mode information, wherein the transmission mode information is included in UE Capability Information Element (IE) of the user equipment if the user equipment supports a half-duplex mode but selects the full-duplex mode.
A user device receives signals from a base station using multiple frequency bands configured with different TDD (Time Division Duplex) settings. The user device, which supports carrier aggregation across these bands with different TDD settings, receives a request for its capabilities from the base station. The user device then sends its capabilities, specifying its ability to operate in full-duplex mode across the multiple bands. Upon receiving carrier aggregation configuration information from the base station, the user device receives signals through the configured component carriers according to its reported transmission mode, which is included in UE Capability Information Element (IE), specifically when the UE supports half-duplex but selects to operate in full duplex.
5. The method as claimed in claim 4 , wherein the UE Capability IE of the first user equipment corresponds to a UE-EUTRA-Capability information element (IE), and the UE-EUTRA-Capability information element includes information about at least one band combination among the two or more bands.
The UE Capability Information Element (IE) mentioned previously for the user equipment corresponds to a UE-EUTRA-Capability information element (IE). This UE-EUTRA-Capability information element includes information about at least one band combination among the two or more bands used for carrier aggregation with different TDD configurations. Therefore, the device reports band combination capabilities using the UE-EUTRA-Capability information element (IE) to the base station.
6. The method as claimed in claim 5 , wherein the transmission mode information corresponds to the band combination.
The transmission mode information (full duplex) reported by the user equipment to the base station corresponds to the specific band combination being used in the carrier aggregation. Therefore, the reported full duplex capability is specific to the chosen combination of bands being configured with different TDD settings.
7. A base station to transmit a signal to a user equipment using two or more bands set in different TDD (Time Division Duplex) configurations, the base station comprising: a transmitter to transmit, to a first user equipment supporting different TDD configurations of an inter-band carrier aggregation, an enquiry message for a user equipment capability, and to transmit, to a second user equipment that does not support an inter-band carrier agreement, an enquiry message for a user equipment capability; a receiver to receive, from the first user equipment, a user equipment capability information message including transmission mode information of the first user equipment, in response to the enquiry message transmitted to the first user equipment, and to receive, from the second user equipment that does not support an inter-band carrier agreement, a user equipment capability information message that does not include transmission mode information of the second user equipment in UE Capability Information Element (IE) of the second user equipment, in response to the enquiry message transmitted to the second user equipment, wherein the transmission mode information of the first user equipment includes information indicating whether the first user equipment operates in a full-duplex mode or a half-duplex mode in two or more bands set in different TDD configurations of an inter-band carrier aggregation; and a controller to determine the different TDD configurations of an inter-band carrier aggregation for the first user equipment according to a report of the transmission mode information of the first user equipment, and to configure a component carrier aggregation comprising component carriers using the two or more bands, wherein the transmission mode information of the first user equipment is included in UE Capability IE of the first user equipment, wherein the transmitter transmits a signal to the first user equipment through the component carrier aggregation according to the transmission mode information.
A base station transmits signals to user devices using multiple frequency bands configured with different TDD (Time Division Duplex) settings. It includes a transmitter to send capability requests to user devices, differentiating between devices that support carrier aggregation across bands with different TDD configurations and those that do not. A receiver receives capability information from the user devices, which includes the duplex mode (full or half) support for devices supporting the inter-band TDD carrier aggregation. A controller then determines the different TDD configurations of an inter-band carrier aggregation based on the UE's report. The controller configures carrier aggregation using these bands, taking into account the user device's reported duplex mode capabilities (included in the UE Capability Information Element). The transmitter then sends signals to the user device according to the configured carrier aggregation, considering the reported duplex mode.
8. The base station as claimed in claim 7 , wherein the UE Capability IE of the first user equipment corresponds to a UE-EUTRA-Capability information element (IE), and the UE-EUTRA-Capability information element includes information about at least one band combination among the two or more bands.
The UE Capability Information Element (IE) in the described base station corresponds to a UE-EUTRA-Capability information element (IE). This UE-EUTRA-Capability information element includes information about at least one band combination among the two or more bands. Therefore the base station uses and interprets valid band combinations as indicated in the reported UE-EUTRA-Capability information element (IE) to ensure correct configuration.
9. The base station as claimed in claim 8 , wherein the transmission mode information corresponds to the band combination.
The transmission mode information (full or half duplex) received at the base station corresponds to the specific band combination reported by the user equipment. Therefore, the base station interprets the reported duplex mode capability as being specific to that reported band combination for the carrier aggregation with different TDD configurations.
10. A user equipment to receive a signal from a base station using two or more bands set in different TDD (Time Division Duplex) configurations, the user equipment comprising: a receiver to receive, from the base station, an enquiry message for a user equipment capability, and to receive control information for configuring component carrier aggregation comprising component carriers using two or more bands set in different TDD configurations of an inter-band carrier aggregation, wherein the user equipment supports different TDD configurations of an inter-band carrier aggregation; a controller to generate a user equipment capability information message including transmission mode information of the user equipment in the two or more bands, wherein the transmission mode information includes information indicating that the user equipment operates in a full-duplex mode in the two or more bands; and a transmitter to transmit the user equipment capability information message, in response to the enquiry message, wherein the transmission mode information is included in UE Capability Information Element (IE) of the user equipment if the user equipment supports a half-duplex mode but selects the full-duplex mode, and wherein the receiver receives a signal from the base station through the component carrier aggregation according to the transmission mode information.
A user device receives signals from a base station using multiple frequency bands configured with different TDD (Time Division Duplex) settings. The user equipment includes a receiver to get capability requests and carrier aggregation configurations from the base station. A controller generates a capability information message including transmission mode information specifying full-duplex operation across multiple bands. A transmitter then sends this capability message to the base station. If a half-duplex mode is supported, but the full-duplex mode is selected, then the transmission mode information is included in the UE Capability Information Element (IE). The receiver subsequently receives signals from the base station through the configured carrier aggregation according to its reported transmission mode.
11. The user equipment as claimed in claim 10 , wherein the UE Capability IE of the first user equipment corresponds to a UE-EUTRA-Capability information element (IE), and the UE-EUTRA-Capability information element includes information about at least one band combination among the two or more bands.
The UE Capability Information Element (IE) within this user equipment corresponds to a UE-EUTRA-Capability information element (IE). This UE-EUTRA-Capability information element includes information about at least one band combination among the two or more bands. The user equipment uses this UE-EUTRA-Capability information element (IE) to communicate supported band combinations to the base station.
12. The user equipment as claimed in claim 11 , wherein the transmission mode information corresponds to the band combination.
The transmission mode information (full duplex) that the user equipment sends to the base station corresponds to the specific band combination being used. Therefore, the reported full-duplex capability is tied to that specific combination of frequency bands configured with different TDD settings.
